- ItemThe CORAS approach for model-based risk management applied to a telemedicine service.(2003-12-10) Stamatiou, Yannis; Skipenes, Eva; Henriksen, Eva; Stathiakis, Nikos; Sikianakis, Adamantios; Charalambous, Eliana; Antonakis, Nikos; Stølen, Ketil; den Braber, Folker; Lund, Mass Soldal; Papadaki, Katerina; Valvis, GeorgeThe CORAS risk management process is based on the Australian standard for risk management and aims at improved methodology for precise unambiguous and efficient risk assessment of security critical systems CORAS addresses security critical systems in general but places particular emphasis on IT security For CORAS a system is not just technology but also the humans interacting with the technology and all relevant aspects of the surrounding organisation and society The use of graphical models in CORAS furthers communication between the different stakeholders of a risk assessment and makes it easier for non technicians to take part Telemedicine services and electronic applications used in the health sector have a high demand for security The medical developers providers and users of such services and systems are important contributors in the risk assessment of these services and systems CORAS has successfully been used to involve medical professionals in the model based risk assessment of a telemedicine system called Tele cardiology in Crete This paper presents the use of the CORAS framework to assess this telemedicine system giving some conclusions on the experience gained
- ItemDifficulties in moving routine medical checks from the specialist level to the general practitioner level.(2005-12-26) Henriksen, Eva; Johansen, Monika; Deraas, Trygve; Arild, EliWe began a project to move routine medical checks for appropriate patients from the specialist level to the patient s normal general practitioner GP The GP s analysis and conclusions would be checked by the specialist using electronic messaging The idea for the project came from the top level of the regional health authority Despite that the project was closed down before pilot testing began We used stakeholder theory as a post project evaluation to analyse what happened and where it went wrong A common mistake in project planning is to focus the planning effort on system tasks and not to pay attention to a well thought out handling of the project s stakeholders This was what happened in our project Ideal objectives and good political intentions are not enough to implement a new e health service
- ItemElectronic symptom reporting by patients: a literature review.(2011-09-06) Johansen, Monika A; Henriksen, Eva; Berntsen, Gro; Horsch, AlexanderA literature review has been conducted to gain an overview of which technologies and patient groups have previously been employed in scientific studies with regard to patients reporting symptoms electronically This paper presents preliminary results from the review based on the abstracts from relevant publications The Medline database search identified 974 publications Of these 235 24 met the inclusion exclusion criteria The number of studies has increased heavily over the past two decades A lot of the studies are small with regard to sample size but we see that the number of studies increase over time Cancer and lung diseases are the largest diagnosis groups Cancer symptom reporting seems to take place inside the healthcare institutions while lung disease and musculoskeletal disease reporting mainly take place at home via Internet
- ItemThe evolution of personal health records and their role for self-management: a literature review.(2014-08-27) Johansen, Monika A; Henriksen, EvaA literature review has been conducted to gain an overview of the evolution of personal health records PHR and their role for self management This paper presents this evolution overview based on review of abstracts from relevant publications in addition to full text review of reviews A search in the Medline database for PHR and self management identified 62 unique publications Of these 90 met the inclusion and exclusion criteria The number of studies per year has increased heavily since the PHR and self management context originated in the early 1990s Nine studies described messaging functionality eleven studies described shared access functionalities and four described both However the general evidence remains sparse to document the value of PHR for self management Most PHRs are not based on patients needs and do not support self management To be adopted by the users and to be useful for self management PHRs need to be integrated with physicians EHR systems and provide shared access both ways in addition to secure e mail communication and educational modules
- ItemPrivacy and information security risks in a technology platform for home-based chronic disease rehabilitation and education.(2013-08-15) Henriksen, Eva; Burkow, Tatjana M; Johnsen, Elin; Vognild, Lars KPrivacy and information security are important for all healthcare services including home based services We have designed and implemented a prototype technology platform for providing home based healthcare services It supports a personal electronic health diary and enables secure and reliable communication and interaction with peers and healthcare personnel The platform runs on a small computer with a dedicated remote control It is connected to the patient s TV and to a broadband Internet The platform has been tested with home based rehabilitation and education programs for chronic obstructive pulmonary disease and diabetes As part of our work a risk assessment of privacy and security aspects has been performed to reveal actual risks and to ensure adequate information security in this technical platform
- ItemRisk analysis of information security in a mobile instant messaging and presence system for healthcare.(2007-07-30) Bønes, Erlend; Hasvold, Per; Henriksen, Eva; Strandenaes, ThomasInstant messaging IM is suited for immediate communication because messages are delivered almost in real time Results from studies of IM use in enterprise work settings make us believe that IM based services may prove useful also within the healthcare sector However today s public instant messaging services do not have the level of information security required for adoption of IM in healthcare We proposed MedIMob our own architecture for a secure enterprise IM service for use in healthcare MedIMob supports IM clients on mobile devices in addition to desktop based clients
- ItemVideo calls from lay bystanders to dispatch centers - risk assessment of information security.(2011-10-24) Bolle, Stein R; Hasvold, Per; Henriksen, EvaVideo calls from mobile phones can improve communication during medical emergencies Lay bystanders can be instructed and supervised by health professionals at Emergency Medical Communication Centers Before implementation of video mobile calls in emergencies issues of information security should be addressed
